What was found
FRAME FOUND CRACKED WHEN ASSIST STEP WAS REMOVED FOR REPAIR. THE FLOOR MUST BE REMOVED TO ACCESS THE ATTACHMENT NUTS. THE BULKHEAD HAD BEEN PREVIOUSLY REPAIRED (AIRCRAFT HAD BEEN INVOLVED IN A GEAR UP INCIDENT IN THE PAST) AND WAS CRACKED PAST THE REPAIR DOUBLER. A NEW BULKHEAD WAS INSTALLED. A CLOSE INSPECTION OF THE STRUCTURE SHOULD BE PERFORMED WHEN THE STEP IS REPAIRED AS THIS MAY BE THE ONLY TIME THE UNDERLYING MEMBERS CAN BE SEEN.
